Python WX - 从 wx 对话框返回用户输入

Question

我是 Python 和 WX 的新手。我创建了一个简单的测试对话框，如下所示，用组合框提示用户。我想从我的主程序中的组合框中获取值。我如何从我的主程序中调用它？

这就是我打算调用它来显示对话框但当前不从组合框中捕获值的方式:

    import highlight
    highlight.create(self).Show(True)
    a = highlight.OnComboBox1Combobox(self)
    print a

对话框文件的名称是“highlight”。下面是代码:

#Boa:Dialog:Dialog2

import wx

def create(parent):
    return Dialog2(parent)

[wxID_DIALOG2, wxID_DIALOG2COMBOBOX1, wxID_DIALOG2STATICTEXT1, 
] = [wx.NewId() for _init_ctrls in range(3)]

class Dialog2(wx.Dialog):
    def _init_ctrls(self, prnt):
        # generated method, don't edit
        wx.Dialog.__init__(self, id=wxID_DIALOG2, name='', parent=prnt,
              pos=wx.Point(264, 140), size=wx.Size(400, 485),
              style=wx.DEFAULT_DIALOG_STYLE, title='Dialog2')
        self.SetClientSize(wx.Size(384, 447))

        self.comboBox1 = wx.ComboBox(choices=['test1', 'test2'],
              id=wxID_DIALOG2COMBOBOX1, name='comboBox1', parent=self,
              pos=wx.Point(120, 16), size=wx.Size(130, 21), style=0,
              value=u'wining\n')
        self.comboBox1.SetToolTipString(u'comboBox1')
        self.comboBox1.SetLabel(u'wining\n')
        self.comboBox1.Bind(wx.EVT_COMBOBOX, self.OnComboBox1Combobox,
              id=wxID_DIALOG2COMBOBOX1)

        self.staticText1 = wx.StaticText(id=wxID_DIALOG2STATICTEXT1,
              label=u'test', name='staticText1', parent=self, pos=wx.Point(88,
              16), size=wx.Size(19, 13), style=0)

    def __init__(self, parent):
        self._init_ctrls(parent)


        ##print get_selection
        ##print get_selection1

    def OnComboBox1Combobox(self, event):
        get_selection = self.comboBox1.GetValue()
        return get_selection

那里有很多对话示例。这里有一对:

• The Dialogs of wxPython (第 1 部分，共 2 部分)
• http://zetcode.com/wxpython/dialogs/

基本上，您需要做的就是实例化对话框，显示它，然后在关闭它之前提取值。典型的做法是这样的:

myDlg = MyDialog()
res = myDlg.ShowModal()
if res == wx.ID_OK:
    value = myDlg.myCombobox.GetValue()
myDlg.Destroy()

更新:这是一个更完整的示例:

import wx

########################################################################
class MyDialog(wx.Dialog):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Dialog.__init__(self, None, title="Dialog")

        self.comboBox1 = wx.ComboBox(self, 
                                     choices=['test1', 'test2'],
                                     value="")
        okBtn = wx.Button(self, wx.ID_OK)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.comboBox1, 0, wx.ALL|wx.CENTER, 5)
        sizer.Add(okBtn, 0, wx.ALL|wx.CENTER, 5)
        self.SetSizer(sizer)

########################################################################
class MainProgram(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Main Program")
        panel = wx.Panel(self)

        btn = wx.Button(panel, label="Open dialog")
        btn.Bind(wx.EVT_BUTTON, self.onDialog)

        self.Show()

    #----------------------------------------------------------------------
    def onDialog(self, event):
        """"""
        dlg = MyDialog()
        res = dlg.ShowModal()
        if res == wx.ID_OK:
            print dlg.comboBox1.GetValue()
        dlg.Destroy()

if __name__ == "__main__":
    app = wx.App(False)
    frame = MainProgram()
    app.MainLoop()
